PATENT LUTHER WENTWORTH, OF CHICAGO, ILLINOIS.

IMPROVEMENT IN WASH-BOARDS.

Specification forming part of Letters Patent No. 129,913, dated July 30,1872; antedated July 25, 1872.

SPECIFICATION.

To all whom it may concern:

Be it known that I, LUTHER WENTWORTH, of Chicago, in the county of Cookand State of Illinois, have invented certain Improvementsin'Wash-Boards; and I do hereby declare that the following is a full,clear,and exact description thereof, reference being had to theaccompanying drawing, which, together with the letters and figuresmarked thereon, forms part of this specification, and in which' Figure lis a front view of a wash-board made according to my invention, and Fig.2 is a side view of same with the removable side piece taken away.

Like letters of reference made use of in the several figures indicatelike. parts.

Nature of the Invention.

clothes being washed.

It is the object of this invention to so construct the wash-board thatwhen a portion is worn out it may be removed and replaced by a new part;and this invention consists in making the corrugations or ribseachseparate and independent of the rest, and of a form so that they may beinserted in transverse slits or grooves cut in the face of thewash-board; and to the end that they may be readily re- .movableandreplaceable, the wash-board is made with one of its side piecesarranged to be readily removed and replaced, all of which will presentlybe more particularly explained and set forth.

GenemZDescription.

Toenable those skilled in the art to make and use my invention, I willproceed to describe the same with particularity, making reference in sodoing to the aforesaid drawmg.

A is the backboard or body of the washboard. B are the sheet-metalridges or corrugations, made of strips of sheet-zinc or other metal,bent into the form shown at Fig. 20f the drawing-that is to say, bentinto a long trough, with the edges turned in, as at b. The face of thebackboard A is sawn or cut transversely by a series of slits, a,arranged in pairs, one pair of slits to each of the ridges B. Theseslits are cut at an incline to the surface of the backboard A, and areinclined alternately upward and downward, so that each pair of slits ifcontinued would cut out a triangular piece of the board. G G are theside pieces, which, prolonged, form the legs or supports of thewash-board. The side piece 0 is made in two parts, the upper part 0 andthe lower part c. This upper part is fastened to the lower part c byscrews or other contrivance, whereby it is rendered removable. Theridges B are attached to the board A by sliding the bent edges 1) intothe slits a when the piece 0 is taken off, and are secured in place byattachiu g said piece.

When one of the ridges becomes worn, it is only necessary to remove thepiece 0 and insert a new ridge, or to change the worn ridge to adifferent part of the board where the wear will be less, and to replaceit with a less worn one. By this means a wash-board may be made to lasta long time. I
